Item - Phone

“Oh, that's right.” Kid put down his completely cleaned plate, wiped his face and hands on the nearby tablecloth, and pulled a small machine from his back pocket. It's an Ultra-Hyper-Transmissive-Wireless-Telephone. It uses the iron and magnesium in the ground below us instead of cables, and we can talk on it even if you're all the way on the other side of the earth. But you can't use it too frequently, because it takes a lot of time to charge. And on top of that, I forgot to add a dial!! So you'll just have to wait for me to call you from my end.”
	“Thank you.” The thing looked like an electronic mosquito repellent coil that had been crushed by an empty can collection machine, but Ness no longer doubted the things Kid said. “It's amazing how small you can make these incredible machines.”
